Should be fine if both versions were in the 8.0.
I have tried restoring databases, on the same controller, after installing much older software(ie from 9.0 or 8.0 to 6.0 or 7.0). After the manual software install went well, the database restore would kill the contoller. Had to stop the boots process, then manually upgrade to a newer version, before restoring sucessfully.
Tried this couple of times.. same result. I beleive someone else posted similar findings, in another thread, months ago.
